Native 4K Tests
What works
- AJA Kona3G (flashed into 4K mode) -> AstroDesign 4K monitor
- HD modes same as for normal mode
- 4K/SuperHD - OK, but see notes
- AJA Kona3G (flashed into normal mode) -> AstroDesign 4K monitor
- 1920i/p - 25fps displayed in left-top quater
- 1920i/p - 29.97 and 30fps OK (fullscreen)
- Blackmagic DeckLink Quad + AJA GEN10 -> AstroDesign 4K monitor
- AJA GEN10 settings (dip switches): HD, HD, BARS, 59.94, 1080
- HD - OK
- SuperHD - OK with sync (50/60i), 29.97/59.94 doesn't work
What does not work
- 2K modes failed in any combination (RGBA/YUV, 24/25/30f) on neither Kona 3G, nor DeckLink HD Extreme
- Generation of 4K testcard on Mac because of insufficient performance (all cores running at 100%)
- unable to nativelly output various modes on Kona 3G (RGBs, 24fps...)
Configuration of the testbed
Note:
- display reports 29.97p (59.94i) as 60i - although works
